            MA736 MagAlpha 8-Bit to 12.5-Bit Angle Sensor
                    MPS’ digital, contactless sensor with 3 μs low latency comes in an ultra-small package that is ideal for space-constrained applications
    

MPS’ MA736 MagAlpha digital angle sensor detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. Its ultra-small UTQFN package makes it an ideal solution for space-constrained applications. Fast data acquisition and processing provide accurate angle measurements from static angle measurement to high-speed rotation. The digital filtering is adjustable to optimize control loop performance when used in servo motor applications.

This sensor supports a wide range of magnetic field strengths and spatial configurations. Both end-of-shaft and side-shaft (off-axis mounting) configurations are supported.

The MA736 detects the strength of the magnetic field and includes configurable thresholds that can be used for diagnostic purposes. An on-chip, non-volatile memory (NVM) provides storage for configuration parameters, such as the reference zero-angle and magnetic field detection thresholds. It is also possible to configure the MA736 with volatile registers without accessing the NVM. The MA736 is available in a UTQFN-14 (2 mm x 2 mm) package.
